Q: Is it my lifters? Or my oil control valve? or oil pump?

asked by on

I put oil in the car and it runs fine for about a hr..lots of power no knocking... After about a hr it has a total loss of power and a knocking starts... I've been told my lifters are shot.... But I've looked online and I see it could be my oil control valve.. My dip stick reads full .. But sounds like no oil is getting to the pistons..... What do I do?
